Transaction Reporting
Definition
The regulatory requirement for investment firms and trading venues to report details of transactions in financial instruments to their national competent authority. Transaction reports enable regulators to detect and investigate market abuse, monitor market activity, and assess systemic risks.
Regulatory Context
Under MiFIR, transaction reports must be submitted by T+1 and include over 65 data fields. EMIR requires separate derivative transaction reports to trade repositories. Regulators regularly impose fines for transaction reporting failures, which are among the most common compliance breaches.
